Securing a stable food chain with increasing urban population over time is becoming a daunting task. The outbreak of Covid19 in 2020 further affirmed the need for indoor self-sustained production of daily use vegetables. In addition, the increased pollution levels at major metropolitan cities demanded the need for healthy indoor air purification plants. Hydroponics is gaining traction as a potential indoor soilless urban gardening method to meet the above needs. The paper talks about means and ways of wireless data acquisition and monitoring of the plant growth, the fertilizer parameters, and the growing media. The work also describes the different non-touch measurement technologies available to accurately measure plant growth and to monitor indoor climatic conditions.
